Meticrane is primarily used as a diuretic in the treatment of hypertension and edema. It works by promoting the excretion of sodium and water from the body, thereby reducing blood pressure and alleviating fluid retention. This makes it effective in managing conditions such as congestive heart failure, kidney disorders, and liver cirrhosis where fluid buildup is a concern. Additionally, it is sometimes prescribed to help control high blood pressure, either alone or in combination with other antihypertensive medications. Its ability to reduce excess fluid helps improve symptoms like swelling and shortness of breath, contributing to better overall patient health.
